Shock Guard TGE Series
- A type that can set a wide range of torque with the same size
- ・The runout can be smaller than that of the TGB series because bearings are used and the center member is attached to that part thru hole.
- ・Both type-1 that can be installed to small diameter sprockets and wide belt sprockets, and type-3 that A type sprockets and belt sprockets can be directly mounted are applicable.
- ・Thanks to automatic re-engagement, you only have to turn the drive side after removing the causes of overload.
- ・The balls and pockets, which transfer the torque, are engaged only in one position because of the unique structure.

Operating principle
Animation showing the operating principle of the TGE Series.
During normal operation (engagement)
The TGE series transfers driving force from the hub to the drive plate on the output side via drive balls (and vice versa).
Bolt a sprocket or belt sprocket directly to the drive plate.
The hub flange has several holes to hold the drive balls.
There are pockets on the drive plate on the output side, and the drive balls are pushed by coil springs via the thrust race to be fitted into the pockets to transfer the driving force.
During overload (trip)
If an overload occurs, the drive balls push the thrust race toward the coil springs and come out of the pockets of the drive plate while rotating to release the driving force.
Then, the cover moves toward the coil springs. Therefore, it is easy to stop the drive source automatically after the occurrence of an overload by detecting the amount of movement of the cover using a TG sensor or a similar device.
Reset method
If you restart the operation after the occurrence of an overload, the drive balls automatically return to their positions within one revolution.
If you continue to rotate the TGE series after the occurrence of an overload, the TGE series is repeatedly reset. Therefore, detect overloads using a TG sensor or a similar device and shutdown the drive source immediately.

Options
TG Sensor
The TG Sensor is a Shock Guard specific proximity switch system overload detecting sensor. After detecting Shock Guard overload (movement of plate in the axis direction), the motor can be stopped and the alarm can be signaled.

Back to topTorque adjustment
1.Read the nut height that corresponds to the required torque from the torque correlation charts and tighten the torque adjustment nut to that height (refer to the figure below).
To tighten the torque adjustment nut, loosen the two setscrews, hook a hook spanner (sold separately, refer to the table below) on the notch in the periphery of the nut, and then turn the nut.
The torque of the product does not always match the correlation chart below, so use it as a guide.
Size | TGE25 | TGE35 | TGE50 |
---|---|---|---|
Spanner No. | FK-0070 | FK-0092 | FK-0105 |
2.When the torque is determined, write down the torque on the nameplate so that you can easily set the torque to the previous value even after an overhaul.
If you mark matchmarks on both the nut and the edge of the hub, you can reset the torque more precisely.
